Okay, so 9-Bit isn't really a thing... yet. Truth be told, we aren't really sure what Comcept had in mind when they announced the stretch goal for an optional "retro-style chiptune soundtrack" and accompanying effects, whether it be 8-bit, 16-bit, or something else, but it looks like we'll get to find out!

The Mighty No. 9 Kickstarter has reached it's next-to-last goal to add this feature to the game, and now only one remains. With less than $200,000 to go and two hours left, will we get the online battle race mode?

The ultimate online competition! You and a friend compete online,
racing to the end of slightly customized versions of single-player
stages. You can see your rival as a "ghost" image in your game, but you
can't affect each other...save for the enemies you defeat being sent
over to impede your opponent’s progress! It's an all new twist on versus mode play that will give Mighty No. 9 life well beyond the single-player campaign!
